Yī-xíng Huì-jué 一行慧覺 (active Tang), Tang Buddhist scholar-monk; the original compiler of the [[KR6e0150|Huáyán jīng hǎi yìn dào chǎng chàn yí 華嚴經海印道場懺儀]] (X1470, 42 fasc.) — a substantial Buddhist repentance-ritual manual for the Avataṃsaka’s ocean-seal bodhi-maṇḍa setting. The ritual was extensively annotated and edited in the Sòng (by 普瑞 Pǔ-ruì) and the Míng (by 讀徹 Dú-chè, 木增 Mù-zēng, and 正止 Zhèng-zhǐ), making it one of the most extensively transmitted Buddhist liturgical works in the Chinese tradition. Yī-xíng Huì-jué’s birth and death dates are not preserved.
(Note: Yīxíng 一行 alone — the great Tang astronomer-monk Yīxíng [Zhāng Suì] 張遂, 683–727, who calculated the Dà yǎn lì 大衍曆 calendar — is a distinct historical figure; the present Yīxíng Huìjué may or may not be the same person, but the catalogues do not equate them.)
